Hi, I'm Ryan — an iOS Developer who loves crafting intuitive, scalable, and user-focused mobile experiences

I specialize in Swift, UIKit, and architectures like VIPER and MVVM, along with reactive patterns using RxSwift. Over the years, I've built high-impact features and contributed to large-scale ecosystems. I care deeply about code quality, clean architecture, and performance — supported by experience with unit testing, CI/CD pipelines, and Agile workflows. Lately, I've been exploring SwiftUI to broaden my approach to building interfaces and keep up with the evolving iOS ecosystem.

I've worked across banking and financial products, building secure and reliable applications used by millions of users. I enjoy transforming complex requirements into smooth, accessible, and meaningful user experiences. My background in Computer Science and training from Apple Developer Academy @BINUS help me approach problems with structure, curiosity, and a strong product mindset.

Besides coding, I find myself enjoying reading about books, exploring meta(most effective tactic) in games and trying out new things — whether it's improving problem solving skills, exploring new tools, or picking up hobbies that keep me inspired. For me, great engineering is a blend of creativity, precision, and continuous refinement — much like mastering a game strategy.

Infosys Solusi Terpadu

Worked and succesfully launched project BYOND by BSI. Has lauched key features for the app's MVP release, including the Umroh feature and the ZISWAF Ecosystem. Using UIKit, RxSwift, and VIPER, I helped deliver a seamless rollout that positioned ZISWAF as the second most popular social transaction feature on the platform, recording a total of 9.7 million transactions. I also initiated and implemented unit testing within my squad, significantly improving code reliability and reducing regressions. As part of the app's UI/UX revamp,

I collaborated closely with design and product teams in an Agile environment to enhance usability and deliver more intuitive user experiences. Additionally, I optimized several user flows—reducing calculation times by up to 70%—resulting in a notably faster and more efficient performance. I also introduced a Git workflow branching strategy to streamline collaboration and maintain code quality across multiple teams.

Apple Developer Academy @BINUS

Collaborated with fellow learners and mentors to solve real-world problems through application development. I worked closely with design and product team members to clarify requirements and ensure alignment throughout the process. By applying Agile methodologies, I actively participated in identifying, estimating, and analyzing requirements during each development cycle. I also utilized version control tools like Git and GitHub to collaborate efficiently with teammates. Over the 10-month program, I successfully developed a total of five native iOS applications.

I am passionate about personal and professional growth, actively seeking new challenges and opportunities to expand my skillset.
